Abstract

An electronic device and a method of controlling the electronic device are provided. A memory and a processor are electrically connected with the memory. The processor controls at least one of a change in a specified operation power, a change in a specified operation clock rate, and an operation state of a diversity module of the electronic device when the electronic device enters an inactive period after an active period associated with transmitting data has ended.

Claims

1. An electronic device, comprising:

a plurality of antennas;

a memory; and

a processor electrically connected with the memory,

wherein the processor is configured to;

when the electronic device enters an inactive period after an active period associated with transmitting data has ended, adjust a state of a diversity module to a turn-on state when a state value of a communication environment of the electronic device including at least one of received signal strength, a transmission speed, or a bandwidth in the active period is less than a predetermined value;

or

adjust a state of the diversity module to a turn-off state when the state value of the communication environment is greater than or equal to the predetermined value.

2. The electronic device of claim 1, wherein after the electronic device enters the inactive period, the processor is supplied a minimum amount of power that is required to maintain a channel connection.

3. The electronic device of claim 1, wherein after the electronic device enters the inactive period, the processor is supplied power corresponding to a first level during a first time, and is supplied power corresponding to a second level during a second time after the first time elapses, wherein the second power is less than the first power.

4. The electronic device of claim 1, wherein the processor is further configured to:

control at least one of a change in a specified operation power and a change in a specified operation clock rate; and

set at least one of a change order, a change time point, a change level of an operation power or an operation clock rate in the inactive period according to the communication environment.

5. The electronic device of claim 4, wherein the processor is further configured to operate using at least one of a predetermined first operation power or a predetermined first operation clock rate when the state value of the communication environment is greater than or equal to the predetermined value.

6. The electronic device of claim 4, wherein the processor is further configured to operate using at least one of a second operation power or a second operation clock rate when the state value of the communication environment is less than the predetermined value.

7. The electronic device of claim 4, wherein the processor is further configured to determining whether to apply at least one of the operation power or the operation clock rate in the inactive period according to the communication environment.

8. The electronic device of claim 4, wherein the processor is further configured to determining whether to apply one of:

a change in each of the operation power and the operation clock rate; and

a change order, a change time point, or a change level of the operation power and the operation clock rate corresponding to a certain period.

9. The electronic device of claim 1, wherein the inactive period includes a period for transmitting a control signal indicating a completion of the data transmission.

10. A method of controlling an electronic device including a processor according to a wireless communication state, the method comprising:

determining whether the electronic device enters an inactive period associated with the wireless communication after an active period associated with transmitting data based on the wireless communication has ended; and

when the electronic device enters the inactive period associated with the wireless communication and a state value of a communication environment of the electronic device including at least one of received signal strength, a transmission speed, or a bandwidth in the active period is less than a predetermined value, adjusting a state of a diversity module to a turn-on state;

or

when the electronic device enters the inactive period associated with the wireless communication and the state value of the communication environment is greater than or equal to the predetermined value, adjusting a state of the diversity module to a turn-off state.

11. The method of claim 10, further comprising controlling at least one of a change in a specified operation power of the processor and a change in a specified operation clock rate of the processor,

wherein the controlling comprises supplying a minimum power to the processor in order to maintain a channel after the electronic device enters the inactive period.

12. The method of claim 10, further comprising controlling at least one of a change in a specified operation power of the processor and a change in a specified operation clock rate of the processor,

wherein the controlling comprises:

supplying an operation power of a first level to the processor during a first time after the electronic device enters the inactive period; and

supplying an operation power of a second level to the processor during a second time after the first time elapses.

13. The method of claim 10, further comprising controlling at least one of a change in a specified operation power of the processor and a change in a specified operation clock rate of the processor,

wherein the controlling comprises setting at least one of a change order, a change time point, a change level of the operation power, or the operation clock rate in the inactive period according to a communication environment including at least one of received signal strength, a transmission speed, or a bandwidth in the active period.

14. The method of claim 13, wherein the controlling further comprises:

verifying the state value of the communication environment; and

when the state value is greater than or equal to the predetermined value, controlling the processor to operate using at least one of a first operation power or a first operation clock rate.

15. The method of claim 13, wherein the controlling further comprises:

verifying the state value of the communication environment; and

when the state value is less than the predetermined value, controlling the processor to operate using at least one of a second operation power or a second operation clock rate.

16. The method of claim 10, further comprising controlling at least one of a change in a specified operation power of the processor and a change in a specified operation clock rate of the processor,

wherein the controlling comprises:

determining whether to apply at least one of the operation power and the operation clock rate in the inactive period according to a communication environment.

17. The method of claim 10, further comprises controlling at least one of a change in a specified operation power of the processor and a change in a specified operation clock rate of the processor;

wherein the controlling comprises determining whether to apply at least one of;

a change in each of the operation power, the operation clock, and an operation state of the diversity module; and

a change order, a change time point, a change level of the operation power, the operation clock, or the operation state of the diversity module corresponding to a certain period.

18. The method of claim 10, wherein the inactive period includes a period for transmitting a control signal indicating a completion of the data transmission.
